During the 2 hour OGTT the participant will complete questionnaires including: a) Medical History Form (e.g., demographics, risk factors, comorbid illnesses, medications); (b) health habits (e.g., smoking, alcohol use; physical activity); (c) psychosocial functioning (e.g., BDI, DISH); and (d) health quality of life. In addition to providing measures of blood glucose and plasma insulin, the blood draw will permit assessment of HbA1c, inflammation, fibrinolysis, and lipids. After the OGTT the assessor will provide the participant with a snack and allow for a brief rest period. Then the RD will conduct a dietary assessment and record the data from the activity monitor. The participant will then be escorted to the Ultrasound Laboratory for assessment of echocardiography, carotid artery imaging and brachial artery endothelial function. At the completion of the session the participant will report to the Assessors, review the days events, be thanked for participating and paid $100 reimbursement for his or her time and transportation.
